Inventor: SASA MICHINARI
IPC: H01L33/40
Filed: 1994-07-20
Abstract: PURPOSE:To reduce the areas of a first electrode for a p-layer and second electrode for an n-layer and improve the luminous intensity of a light emitting element by forming the electrodes in very small areas at corners on the surface of the p-layer and forming lead wires to the electrodes by wedge bonding. CONSTITUTION:N-type layers 3 and 4, a p-type layer 6, and light emitting layer 5 interposed between the layers 3 and 4 and 6 are formed in the form of homojunction etc., by using a group III nitride semiconductor. A first electrode 7 and second electrode 8 are formed in strip-like states on the p-layer 6. The electrodes 7 and 8 are connected to lead pin lands through wedge-bonded A lead wires 21 and 22. Consequently, the electrodes 7 and 8 can be formed in minimum areas at corners on the surface of the layer 6. Therefore, the luminous intensity of a light emitting diode can be improved by reducing the shades of the electrodes 7 and 8 formed by the light emitted from the diode.

Title: Flow rate controller of branch line
Inventor: NISHIMURA YOUICHI
IPC: G05D11/13
Filed: 1983-10-13
Abstract: PURPOSE:To obtain a flow rate controller which is capable of an even load distribution by using a controller for opening amount of control valve which uses the maximum value of a flow rate controller of each branch line as an input. CONSTITUTION:The set values of flow rate controllers Co1-Co4 are cascaded in common from the output of a valve opening amount controller 11. Therefore the flow rate is equal among branch lines L1-Ln. If the load (pipeline resistance) of a certain branch line increases, the flow rate controller of said branch line increases the opening amount of a control valve by an amount equivalent to the load increment to set the same flow rate as other branch lines. When the output MV of a flow rate controller exceeds the set value of the controller 11 with said increment of load, an excess load is decided for the branch line. Thus the operation output MV is reduced to decrease the set value to be given to other lines. In this way, the flow rate of each branch line is decreased.

Title: Detector of underground metal conduit
Inventor: WATABIKI MASAYUKI
IPC: G01V3/11
Filed: 1987-08-03
Abstract: PURPOSE:To securely detect possibility for damage from a conduit system side by connecting a resonating circuit in which detecting current is resonated to vary in high impedance between an underground metal conduit and a corrosion preventing device. CONSTITUTION:Earth points i, i+1,... are provided at prescribed intervals on a conduit 1. On the other hand a detector 2, a power source 3 and resonating circuits 4 are connected to a conduit system 1 at a point i, and the earth side is linked to a corrosion preventing device 7. In the case where an excavator 5 damage the conduit at a damage part 6, the voltage and the current of a signal varies because the impedance is considerably low at this point. This variation is grasped by the detector 2. Further, in regard to the deciding of the damage part 6 time difference of damage signals from each point at which the detector 2 receives is computed at a relay point or at the center. Since the resonating circuits 4 are inserted at each earth part i, i+1, ..., and high impedance is formed for the signals of the power source 3, the current signal is very little from the conduit system 1 to the earth and so the signals go on long distance.
